Plz give me answer of this question
Q.4. Arrange the following as per the instruction given in the brackets:
(i) He, Ar, Ne (Increasing order of the number of electron shells)
(ii) Na, Li, K (Increasing ionisation energy)
(iii) F, Cl, Br (Increasing electronegativity)
(iv) Na, K, Li (Increasing atomic size)
Dear student,
Answer
1. He< Ne<Ar
(The number of shells increases down the group)
2.K<Na<Li
(Ionisation decreases down the group)
3. Br<Cl<F
(Electronegativity decreases down the group)
4. Li<Na<K
(Atomic size increases down the group)
Regards.
